  • Copper and its alloys have long been recognized for their antimicrobial properties. The first recorded medical use of copper dates to between 2600 and 2200 BC, when the Egyptians were reported to have used copper for sterilizing chest wounds and drinking water ( 10 ).
  • Several copper alloys have been developed in which the grain size is stabilized by the presence of a finely distributed second phase. Examples include copper-iron alloys such as C19200, C19400 and C19500, and aluminum-containing brasses and bronzes such as C61500, C63800, C68800 and C69000.
  • the alloy loses its characteristic lightness, to the advantage of some of the mechanical properties. The most important are those in which copper is the principal constituent. These are (iii) Heavy alloys of great strength. The alloys of aluminium, which can thus be divided into three groups, are very numerous, and there can be no question
  • Copper and its alloys. Copper is a valuable metal. The copper alloys are more widely employed. The alloying of copper with other elements increases the strength of the metal in some cases and improves the anticorrosive and antifriction properties in others.
  • The different metals that are used to prepare alloys are zinc, copper, tin, aluminum, chromium, nickel, silver, etc. Moreover, the different non-metallic elements used to make alloys are carbon, boron, sulfur, zinc, etc. Depending on the composition of metal or non-metal in the alloy, we have different types of alloys being formed.
  • Two additional characteristics of copper and some of its alloys are high thermal conductivity, meaning that preheat is required for many joints, even at quite modest thicknesses, and the high coefficient of thermal expansion, meaning that distortion can be an issue with root gaps rapidly closing during welding .

  • Jul 10, 2015 · Common alloys include brass (an alloy of copper and zinc), bronze (traditionally copper and tin, but other elements can be used), and copper–nickel alloys. The outer surfaces of U.S. coinage—nickels, dimes, and quarters, among others—are made from copper–nickel alloys.
  • Aug 10, 2018 · Previously, most studies on the antimicrobial properties of copper alloy surfaces focused on either the killing kinetics or the applicability of copper alloys in infection prevention [7,9,10,19,20]. There are, however, only a few studies that investigate the compatibility of chemical disinfectants with copper alloys [ 12 – 14 ].

An alloy of mercury with another metal is called amalgam. Alloys are usually harder than their components but very often less ductile and less malleable. Thus the hardness of gold is increased by addition of copper to it. The melting point of an alloy is always lower than the melting points of the constituent metals.
